When I start a New project and try to export a clip I get, Hitfilm Pro could not encode frame 1 (error 36). However when I open an Existing Project and import the same clip for export, everything works fine. Is anyone else having this issue?
Are you using the same export preset in both instances? A little more detail about the project, footage, export options, etc. would be helpful.
[EDIT] Also, please list your system specs per this sticky:
